Miles-LaGrange was nominated by President Bill Clinton on September 22, 1994, to a seat on the United States District Court for the Western District of Oklahoma vacated by Lee Roy West. She was confirmed by the United States Senate on October 7, 1994, and received her commission on November 28, 1994. She began her service as chief judge in 2008. Judge Miles-LaGrange's preliminary ruling [5] enjoining amendment of the Oklahoma Constitution to prohibit the state's courts from either "considering or using" international law or Islamic Sharia law has attracted considerable attention and has prompted one Oklahoma state legislator to urge Congress to impeach her.[6]
